Executive Summary

We disassembled, analyzed, and reassembled a Black & Decker power drill.

We took each component of the drill apart and analyzed it to determine the function and why each part was made of it material and shape. This helped us better understand how the drill worked on the component level.

By analysis and research we were able to determine what the component was. We also produced CAD drawings and pictures of each component. After all this information was gathered we reassembled the drill.

Assembly was

After we disassembled, analyzed, and reassembled the Black & Decker power drill we gained a better comprehension of how the drill works.

Introduction

This product is a Black & Decker Drill which is built to use different size bits to drill holes in various materials. The drill also has a reversable function. This is accomplished by changing electrical energy into mechanical energy inside the drill motor.

Before Disassembly

Purpose

The Black and Decker Drill is used to drill holes into various materials (ie. wood, sheetrock). The drill uses an AC current from a wall and directs electricty to a motor to create rotational motion. This motion is transferred to the gears in order to create rotation within the drill bit.

Operation

The product works and runs smoothly by changing AC power from a power outlet into mechanical energy in the drill to turn the bit. This is demonstrated best when the drill's trigger is pulled because you can hear the motor and the cooling fan rotating.

Amount of Components

We estimated that the drill is made of approximately ten components. These ten components include:

Motor

Trigger switch

Cord

Drill bit

Level

Cooling fan

Casing

Direction switch

Trigger lock

Chuck

Screws

Gears

Types of Materials

We estimated that the drill is made of approximately five materials. These five materials include:
